I understand the concept with Ceph being able to recover from the failure of an OSD (presumably with a single OSD being on a single disk), but I'm wondering what the scenario is if an OSD server node containing multiple disks should fail. Presuming you have a server containing 8-10 disks, your duplicated placement groups could end up on the same system. From diagrams I've seen they show duplicates going to separate nodes, but is this in fact how it handles it? ------------------------------------------------------------------------------ CONFIDENTIALITY NOTICE: If you have received this email in error, please immediately notify the sender by e-mail at the address shown.
